Question 9. The perimeter of a square is 68 cm . Use an equation to determine its side length - Workspace

To determine the side length of a square when the perimeter is given, follow these steps: ### **Step 1: Understand the Formula for Perimeter of a Square** The perimeter \( P \) of a square is calculated using the formula: \[ P = 4 \times \text{side length} \] Let's denote the side length of the square as \( s \). ### **Step 2: Set Up the Equation** Given that the perimeter \( P \) is 68 cm, substitute the values into the formula: \[ 68 = 4s \] ### **Step 3: Solve for the Side Length \( s \)** To find \( s \), divide both sides of the equation by 4: \[ s = \frac{68}{4} = 17 \, \text{cm} \] ### **Conclusion** The side length of the square is **17 cm**.
